To all whom it may concern: at i. The other ends of the cable conductors Be it known that I, FRANK L. SEssIoNs, a are respectively connected to the fixed posiv citizen of the United States, residing at tive conductor at aremote point,and the neglumbus, in the county of Franklin and State ative or return conductor-to some grounded of Ohio, have invented certain new and useobject as the track rails in the main entry ful Iin rovements in Electric Vehicles and near the fixed conductor. The fixed con Oableeels, of which the follovdng is a speciductor referred to is an insulated Wire adapted fication, reference being had therein to the to have a trolley wheel contact therewith. accompanying drawing. f The fixed. conductor and its opposite return 7 10 This invention relates to improvements in conductor (as the track rail) are, in a mine, in the devices by which an electric locomotive the main entry. Expense will not permit the or other vehicle can be he t in electric conestablishing of these fixed conductors in all nection with a more or less distant fixed of the branch entries or side entries and in the conductor. various rooms throughout the mine, and it is 15 A -mecha1iism embodying my improvein these latter places that use is made'of the ments is particularly well adapted for use in reel conductors. As the carGmoves from the the operating of coal mine locomotives such fixed conductors, it pays out the cable.

' In the drawings, I have selected a coal When it is desired to takeup or cause the mine locomotive as a means of illustrating winding of the cable upon the reel,the wheel one of the ways in which my improvements 7' is moved into engagement with the car can be employed. wheel 9. The Wheel 7' is mounted on an 35 The locomotive shown in the drawings is arm or frame at K, pivoted at k.

When thisis G indicates as an entirety the car or vehiturned in one direction, it not only permits cle which carries the winding mechanism, it the rod L to move longitudinally, with the v 45 reingadapt'ed to move along the tracks at result that the bar or frame K is allowed to A and having the wheels 9 g fitted .to-the move downward, but the threaded devices tracksinsure 'afiositive force of the arts referred The winding mechanism F includes-with to, At there is a Weight w ich tends to other parts a reel H mounted in suitablesup- .drawthe bar on frame K and the friction 50' ports on the car. To this reel are connected wheel {downward I have found a weight 1 5 I the ends ofthe positive and negative conof this characterinm'any respects su'periorto ductor sections of wire respectively -insuthe spring heretofore used by me; it ma n lated but bound together .inthe form of a tains the contact-of the frictional parts more cable Litheend of the negative conductor firmly and steadily. Adjacent to the fric- '55 being shown at i,- and that of the positive tion wheel there is a brake device N, here consisting of a curved plate or bar secured to the car, and having the operative curved part a so disposed that as the wheel rises, it comes against this plate and is stopped in its rotation, and this in turn causes a stoppage of the turning of the winding reel. The reel .is mounted on frame bars 0 O secured by the bars 0 to the frame or body of the vehicle.

. When the operator desires to let the cable pay out, he draws the rod L forward longitudinally, this resulting in the lifting of the swinging frame K, releasing it from the track wheels, and shortly thereafter a frictional engagement is attained of this friction wheel with the brake device at N, and such engagement he has under his control, in-

creasing or decreasing the freedornof rotation for the reel as he deems necessary. When he desires the cable to be automatically taken up, he forces the rod L in the other direction, the screw and the weight bringing the arm K and the friction wheel 7' tightly against the track wvheel, and thereupon through the sprocket gear the reel is wound in such direction as to take up the cable.

' The reel terminals of the negative and posianism is an automatically acting cable.

guide adapted to direct the cable both as it pays out and as it is taken up, The copper conductors in such cables .are expensive, and the breaking that results from freqfliently bending them back and forth s ould be avoided.- To avoid unnecessary bending of the wires and. to insure that they shall be always properly flexed as they are ranged leaving the drum or are approaching it, it is requisite that the cable should be accurately guided. This I accomplish by the devices illustrated. P is a traveler having a framework p, a vertically arranged grooved wheel p and two horizontally'arrooved wheels 0 the grooves on these; being so related to each other that an anti-friction passageway is provided for the cable, the walls of which give it uniform sup ort at all times. This traveler is moved bao and forth parallel to the axis of the drum by an actuating mechanism properly timed relatively to the revolutions of the druin. As shown, it consists of the shaft Q having a right hand thread and a left hand. thread arranged to intersect each other, and

a projection It carried by the traveler P.

eiaeii This projection fits in the threads and 1', first one and then the other, the thread grooves at the ends of the shaft terminating in circular grooves which permit the projection R, after traveling through one of the grooves, to ass to the other and return. The pitch of the threads and the s eed of rotation of shaft Q are arranged so t at the resultant vmovement of the traveler corresponds with' that of the'convolutions of the cable as it wraps .u on the drum. The shaft Q is driven from the drum by sprocket gear having the chain Sengaging with the driving sprocket s on the drum shaft and the sprocket s on the shaft Q. The traveler P is suitably su ported by a guide at T. When the cab e is unwinding, the shaft Q is turned in one direction by the sprocket gear, and it advances the traveler in such way that the convolution of the cable which is leaving the drum passes directly throu h the anti-friction guideway. And on t e other hand, when the cable is being taken up and power is applied from the car wheel. g

to the drum, the latter imparts a reverse rotation to the shaft Q, and the traveler is moved in the o posite direction to guide the cable as it win s on the drum.
